[DotNetDevelopment] image handling in vb.net 2008 (visual studio)

[ngugi]

am handling an application that will be used as a student manager, and
i need to store the student`s photograph as well as the
guardian`s.....its a cropper for me :=((....could anyone show me how
to go about attaching an image,that way an image can be
scanned,checked for size e.g 300 *300 dpi and then save it in a
database, and what is the most suitable data type for this type of
complex data? thank you
